Horsetails are perennial non-flowering plants in the Equisetum genus of the horsetail family. Many of them are native to the Yuba-Sutter area.
Horsetails may be considered "living fossils," because they constitute the only surviving genus in the entire class Equisetopsida, which was very diverse and widespread in the late Paleozoic era, when some Equisetopsida grew to 30 meters tall. Their closest surviving relatives are ferns. Like ferns, horsetails reproduce via spores.
Common Field Horsetail
Common field horsetail is a one-foot-tall horsetail that is native to Yuba County and typically grows at elevations below 9,500 feet. It is found in central oak woodland, valley grassland, yellow pine forest, and riparian forest. It tolerates partial shade and is equally likely to grow in wetlands or non-wetlands.
